    10 Minute Exposure of Milky way.

    Hi all,

    This is a test images of the Milky Way. Total time exposed is 10 minutes, but I broke it down to 5 x 2min exposures. Taken with a Canon 400D, 17-40mm Lens @ 24mm (17 on lens )

    Taken on new tracking system I made. Insert shows a 100% crop.

    Andrew.

    Gee, Astroman! I'm confused. You have the post in the NFC section and yet you show C+C always appreciated. Anyway, I'd like to know about the tracking system you made, and was wondering about the exposure settings for each shot. Am.
    CC, Image editing OK.

    Nothing to worry about thar on the camera you should see a symbol (white on most modern cameras) a circle with a line through it.

    That would be where the film would be in a SLR so its a distance to film/sensor + the lens

    Or so i understand i could be wrong

    Nice photo by the way very interesting.

    very interesting - I didn't know you could make your own tracking system? I always thought it would be frightfully technical and expensive too

    Umm yeah, oops, it's on my signature. I out it here because it was a simple test shot which wasn't a final image, so thats why I put it here, maybe the wrong section for it, but if the mods are happy for it to be here, then okay by me, maybe better off somewhere else

    Anyway, the tracking device I used is a modified Automatic Gate opener and Stepper motor controller. I have been running it for some time adjusting it slightly here and there to get the speed right. Here is a pic of it while I was working out a way to mount it, havent got a final pic yet. Been too busy cleaning up an old Metal Lathe I got.

    I actually had to travel 30 minutes out of Adelaide to shoot this image, you can still see some light pollution on the right hand side of the image.

    very interesting Astro, I am going to be going on an outing one of these days with a bunch of Astro nuts.
    The stuff they use is mind boggling, but your little invention is just the ticket, as it does the job very well mate.

    I am going to have to get off my but and work out when I can get out with them, might if I remember give you a yell as well.

    Peter

    I'm always amazed at what you present.
    I think what makes it spectacular for me is that I know it's out there but you bring it in here.
    Brilliant.

    Fantastic shot Andrew, I bumped into David Malin a couple of times last year both in Sydney and at the Parkes radio telescope and I reckon you guys are crazy staying up all night.

    This is a re-occurring hoax that pops up every August, especially the bit claiming Mars as big as the moon. It spawned out of the closest approach of Mars to earth in 2004. At present Mars is quite small through a scope and getting smaller in the near future
